Tube sampling of Pitsea cell MSW

submitted by: watson_gvr

This video shows a 320 mm diameter, 0.5 m long, steel tube being pushed into highly compressed MSW (waste) inside the 2 m diameter Pitsea compression cell in real time. The tube is being pushed by the upper platen of the cell. This formed part of an experiment to investigate the possibility of recovering undisturbed tube samples from MSW.

EPA 525.2 for the Analysis of Organic Contaminants in Water (Webinar)

submitted by: Chrom Solutions
This webinar reviews EPA Method 525.2 (SPE-GC-MS method) for the analysis of organic contaminants in drinking water. In order to achieve the low detection limits, water samples are extracted and concentrated prior to injection into the GC-MS. Automated systems remove the laborious, less accurate steps of vacuum systems and at the same time, save solvent and cost less overall. Speakers: Beau Sullivan (Santa Clara Valley Water District), Richard Jack (Thermo Fisher Scientific). Visit...

Pesticides and Herbicides: A Growing Concern (Webinar)

submitted by: Chrom Solutions
This webinar describes using suppressed ion chromatography--mass spectrometry (IC-MS/MS) for glyphosate (a widely used broad-spectrum herbicide) analysis with the result that required reporting limits can be achieved without time-consuming derivatization. In addition, a validated extraction method for weathered toxaphene (banned since 1990) and its degradation products in fish tissues using Accelerated Solvent Extraction is also discussed. Speakers: Diana Burdette (US EPA R4 SESD), Stuart...
